--- Comment #1 from Darren Tucker <dtucker at dtucker.net> ---
It's probably not inetd-mode in general since a lot of our tests use
that (they use ssh to invoke sshd -i as a proxycommand) and these are
regularly invoked hundreds of time across many configurations,
including some ARM and ARM64.

Given this report is for ARM, I suspect this may be some variation on
the seccomp filter issues (eg bug#3702) which are dependent on kernel,
glibc and header versions present at compile time.  Can you describe
the host system some more?  Distro, kernel, glibc version, hardware?

Can you attach the logs from the server during a failed connection? 
Either from syslog or use sshd -E to write the log someplace.

If the problem is related to the seccomp sandbox, one other thing that
might shed some light is to build with sandbox debugging enabled (but
note that this is not safe for production use):

./configure --with-cflags=-DSANDBOX_SECCOMP_FILTER_DEBUG

then build, install and generate a new log.
